Improvement in pumps



UNITED STATES M. J. ALIHOUSE, OF WAUIUN, WISCONSIN.

lMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 4l,16, dated January12, 1861.

To @ZZ whom t may concern.-

Beit known that I, MILO J. ALTHOUSE, of the city of Waupun, county ofFond du Lac. State of Wisconsin, have invented a new and Improved Modeof Constructing Wooden Pumps; and I do declare that the following is afull and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,making a part of this specification, in which- Figure l is a perspectiveview of the pump; Fig. 2, a perspective view of one of the longitudinalhead-bolts that conne the pin or fulcrum to which the handle isattached; Fig. 3, a plan section ot' the barrel and piston of the pump.

The nature of my invention consists in constructing wooden pumps in sucha manner as to greatly increase their durability and efficiency, makingthem much less liable to get out of order, and easier repairedwhennecessary. v

lo enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

The manner in which I construct my pump will be seen by reference to theannexed drawings, in which- Letter A, Fig. 1, represents the cap or topof the pump; letter B, the body ofthe pump; C, the barrel in whlch thepiston works; D, the pipe that connects with the water; E, the spout; F,the handle; G Gr, two bolts that confine the pin or fulcrum H, to whichthe handle is attached by which the pump is operated.

Fig. 2 is a perspective view of the bolts G. The objects of these boltsare to prevent the pump .from splitting, to confine the pin or fulcrumH, and retain it in its proper place. It will be seen, Fig. l, G G, thatthese bolts pass through. the pump in the opposite direction to the pinor fulcrum H, and that the pin or fulcrum H passes through the heads ofthese bolts on its way through the pump and handle. These bolts, beingprovided with a screw and nut, when tightened up, secure the pin orfulcrum H firmly in its place, and the tendency of the pump to be splitby the pressure on the pin is et't'ectua-lly obviated. Should the pin H,by constant use, ever become loosened, as is very commonly the easewithout the bolts, it can easily be tightened again by means of the nutsand screws.

Fig. 3 represents a plan section of my improved barrel with the pistonproperly placed therein; but in the ordinary wooden pump the barrel isformed out ofthe same material as the stock or body of the pump byboring out one end of the barrel for the piston and by fitting the otherend of the barrel into the stock or body of the pump, and frequently byboring out the bottom of the stock or body of the pump itself. It beingnecessary for the piston to lit the barrel perfectly tight, there willbe more or less wear upon the parts in contact. Consequently, thisportion of the pump is frequently the first to need repairs or wear out.Should the part worn out be the barrel, it would be necessary to supplya new one, if made in the ordinary way, but if made after my plan,fifteen minutes would make it as good as new; but should it be made inthe bottom of the stock or body of the pump, it would be necessary toreplace it with a new pump. To obviate this diiiiculty as much aspossible I use hard maple for my barrels, a species of wood that isexceedingly hard, smooth, and durable, and make the barrels two and ahalf or three feet long with a uniform hole in them, so that I can usethe piston in one end until it is worn out, and then turn the other endand use that until that is worn out, thus actually more than doublingthe durability of the pump without increasing its parts or expense. Thevalve and piston being liable to derangements, the ease of accessthereto by my plan is another important consideration, requiring simplyto disconnect the barrel from the stock, or body of the pump from thebarrel. The piston can then be taken without taking the handle orpiston-rod from the pump. Another important consideration is thesmoothness oi the barrels when made of hard maple, and the ease withwhich they work.

In connecting my pump top or stock with the barrel I turn it off in sucha manner that when inserted into the barrel it will make a perfectjoint, simply requiring to be put togather when taken apart @o be incomplete pinv H, when constructed and applied to a Working condition.pump-stock, B, substantially as shown and After nhus fully describingthe constr'ucdescribed.
